Assertion `(A) : Cu` gets readily corroded in acidic aqueous solution.
Reason `(R) :` Free energy of the process is positive.

A

if both assertion and reason are true and reason is thr correct explanation of assertion

B

If both assertion and reason are true but reason is not the correct explanation of assertion

C

If assertion is true but reason is false

D

If both assertion and reson are false.

Text Solution

Verified by Experts

The correct Answer is:
D
Non-oxidising acids (HCl and dil. `H_2SO_4 `) do not have any effect on copper . However they dissolve the metal in presence of air . As it is non-spontaneou process so.`Delta G ` can not be-ve
